Packaging box for steak fresh keeping and refrigeration

Abstract

The invention belongs to the technical field of food refrigeration, in particular to a packaging box for steak fresh keeping and refrigeration. The packaging box comprises a box body, a box cover, a rectangular air bag, clamping modules and a supporting module. The clamping modules and the supporting module are arranged inside the box body, the bottom of the box body is provided with a first cavity, the inner side of the first cavity is provided with a water absorption module, the bottom ends of the two clamping modules are elastically connected with the two sides of the supporting module correspondingly, the box body is covered with the box cover, the rectangular air bag is arranged inside the box cover, a valve is arranged on the box cover, the valve communicates with the rectangular airbag through a conduit, two first telescopic air bags communicate with the positions, corresponding the two clamping modules, of the bottom of the rectangular air bag, and the bottoms of the two firsttelescopic air bags are in contact with the tops of the two clamping modules correspondingly. The box body is sealed through the rectangular air bag, the box body refrigeration efficiency is improved, melted ice water is reused, and box body heat insulation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of food refrigeration, in particular to a packaging box for steak freshness preservation and refrigeration. Background technique [0002] Food refrigeration refers to a food preservation method that pre-cools perishable food and then stores it at a temperature slightly above freezing point. The main purpose of food preservation is to eliminate the toxicity hazards of microorganisms, prolong the storage period, and maintain its nutrition and sense. During the preservation process, the gas composition is changed by packaging, combined with low temperature, so that the food has a better fresh-keeping effect. For example, the steak sold in the supermarket needs to be transported from the warehouse to the shelf for a short distance in the hot summer. Due to the high temperature, the steak needs to be transported in refrigerated packaging to avoid softening and deterioration of the steak. At the same time, the wa...

Problems solved by technology

However, when this type of food refrigeration equipment is used to seal the packaging box, it only adopts the method of closing the lid. However, in the process of transportation, the packaging box will shake and it is easy to cause gaps in the lid during the transportation process, so that If the cold air overflows, the refrigeration effect of the food in the equipment will be reduced, and it will easily deteriorate and cause waste.
